SUCTION MEMBER FOR WASZEZIIIG- MACHINES.

Application filed March 16, 1925.

To all whom it may concern:

Be .it known that 1, Hanna F Knnnucn, a citizen of the United States,and a resident of Perrysburg, in the county of lVood and the State ofOhio, have invented a new and useful Suction Member for-WashingMachines, which invention is fully set forth in the followingspecification.

My invention has for its object to produce a means for greatlyincreasing the efficiency of the tilting or wave form of washingmachine, wherein the agitation of the soapy water and the clothes isproduced by a means for causing the water to rise above and dash uponthe clothes such as by swinging or tilting a receptacle containing waterand the clothes. The improvement may be embodied in any well known typeof tilting washing machine as well as in any type of machine havingmeans for raising and lowering the water level in any part of thecontainer that contains the water and the clothes. In the preferred formof the invention there is provided a member having a plurality ofopenings, the member being spaced from the bottom portion of thecontainer and so located that portions of the member will be alternatelybrought above the surface of the water by the movement of the water inthe container, or relative to the container, whereby air and water vaporwill be drawn by the lowering of the water or will be forced therefromby the rising of the water beneath portions or parts of the member. In amore specific form the member is provided with a plurality of cells toassure a dis tribution of the suction over the surface of the member. I

The invention may be contained in structures that vary in form and maybe used in connection with washing machines of different types. Toillustrate a practical application of the invention and to fullydescribe a structure containing the invention, l have selected as anexample a structure ontaining the invention and shall describe ithereinafter. The structure selected is shown in the accompanyingdrawings.

Figure 1 illustrates a typical wave action washing machine containing myinvention, in section. Fig. 2 illustrates the wa hing machine in aposition different from that shown in Fig. 1, and Fig. 3 illustrates thethird extreme position of the machine. Fig. 4 illustrates a section of asuc- Serial No. 15,754.

plane of the line 66 indicated in Fig.

Fig. 7 is a broken sectional view taken on the broken line 7'? indicatedin Fig. 5.

In applying my invention to theordinary tilting or wave type of washingmachine the bottom wall of the container for the clothes and water ispreferably provided with a depression and a perforated member so locatedas'to substantially cover the depression, whereby the air and vaporpressure will be varied to produce increased or decreased pressure ofthe air and vapor and cause movement of the air and vapor to and fromthe depression and consequently through the clothes or fabric that maybe lying upon the surface of the member.

In Figs. 1 and 2 the container 11 may be upported on a suitable standardsuch as the standard 12 and actuated by means of the shaft 13, toproduce tilting movements in the manner well known in connection withsuch machines.

The container 11 is provided with a member that separates the containerinto two parts or chambers. Preferably the bottom of the container isprovided with the depression 14 and a cellular member 15 is located inthe depressed portion of the container. andso that the top of thecellular member 15 will be located substantially in the plane of thebottom of the body portion of the container, thatis, the plane thatforms a continuation of the'curved walls with which the containers ofsuch washing machines are usually provided. The memno 15 is providedwith a top 16 having openings 17. Preferably the top 16 is corrugated,it being provided with corrugations 18, that extend across the directionof movements of the water and the clothes when the container 11 isagitated by the oscillatory movements produced by the shaft 13. Themember 15 is sub-divided into chambers or cells by means of the parallelwalls 19. The chambers that are thus formed extend across the member 15,that is, along the under side of the top 16 and the corrugations 18. Itwill be observed that the lower ends of the walls 19 are spaced from thebottom of the depression 14 thereby forming a channel 23 for the passageof liquid, this passage being common to all the cells.

When the container is tilted about the axis of the stub shaft 13, thewater moves along the top 16 of the member 15 and the curved side wall,and is thrown over towards the opposite side in wave breaker form anddashes on to the top of the clothes in the manner well known in the art.This movement of the container 11 carries the bulk of the water from thebottom of the container, and the water that was in one end of the member15 moves along the bottom of the depression lat through the channel 23,and thus the water in the cells of the member 15 and one end of themember is carried dowir tothe lower end of the tilted member. This drawsthe mist or vapor formed by the dash ing water within the container 11through the clothes, particularly, those parts that are e in contactwit-h that end of the top of the On the return of the container member15. 11 the air is forced out of that part and through the clotheslocated on the top. On further movement of the container 11 the otherend of the member 15 is emptied, the water flowing along the bottom ofthe depression in the channel 23. This again prod uces suction at thatend and on the reverse movement of the container 11 the air and vapor isforced from that end of the member and drawn in to the end firstreferred to above. Therefore, as the container is oscillated back andforth. throwing practically all the water from the bottom, and

- a large part of the water from the depression, there is an alternatechange of pressure above and below atmospheric to cause movement of theair and vapor through the openings 17 of the top 16. This would alsooccur if the member was formed only of the top 16, but by subdividingthe space below the top 16 into small chambers, a distribution of themovement of the air into and out from the member 15 is insured. Thismovement through each and all of the openings may be made more positiveand more certain it the chambers are subdivided by partitioning wallsthat extend the length of the member 15. In the form of constructionillustrated in Figs. 5, 6, and '7, the member 15 is provided with thepartitioning walls 22 that are located in a direction transveise to thepartitioning walls 19. The openings 17 are located on oppositeaslopingsides of the corrugations and between the walls 22 so'that the upperends of the cells formed by the partitions 19 and 22 communicate withthe interior of the body portion of the container .11, through twoopenings through which the vapor and steam may be drawn into each of thecells or forced therefrom depending upon the change of level of theliquu: in each of the cells.

I claim:

1. An oscillatory washer having a chamber in the bottom thereof, cellsin said chamher having open outer ends spaced from the bottom of saidchamber thereby providing a channel common to all of said cells, and theinner ends of said ells being provided with restricted openings toafford commnnication with said chamber through said rcstrictcd openings.

2. In a tilting fabric washing machine. a container having a recessedpart in the bottom thereof and for containing a washing fluid and thefabrics, an open bottomed cel lular member spaced fiiom the bottom ofsaid recessed part thereby providing a channel'and having openingsextending over the recessed part of the container and located in therecessed part of the container, the openings being located in the upperends of the cells.

In a tilting fabric washing machine, a container having a recessed partin the bottom thereof and for containing a washing fluid and thefabrics, an open bottomed cellular member spaced from the bottom of saidrecessed part thereby providing a channel and having openings extendingover the recessed part of the container, and located in the recessedpart of the container, the open ings located in the upper ends of thecells, the top surface of the member having cor rugations extendingacross the path of the movement of the water and fabric when agitated bythe operations of the machine.

at. In a tilting fabric machine, a container having an oblong depressedportion, a normally submerged member having a perforated corrugated topand located in the depressed portion, said member also havinglongitudinally and transversely extending walls forming open bottomedcells that communicate with the body portion of the container throughthe perforations. the lower ends of said walls being spaced from thebottom wall of the depressed portion thereby providing a channel commonto said cells for the passage of fluid therethrough.

An oscillatory washer comprising a receptacle, a cellular member in saidreceptacle the cells having open outer ends spaced from the bottom ofsaid receptacle, thereby providing a channel common to all of said cellsand the inner ends of said cells being provided with restricted openingsto afford communication with said receptacle.

In testimony whereof I have hereunto signed my name to thisspecification.
